"That was curious," he said, "very curious. Was anything else damaged? Furniture and so forth?"

"I don't know. Mrs. Clayton said nothing of it, and I didn't ask her. But it was quite bad enough as it was. The decoration was really good, and I can't conceive a meaner piece of tomfoolery than such an attack on a decent woman's property."

Then Hewitt talked of other cases of similar stupid damage by creatures inspired by a defective sense of humour, or mere love of mischief. He had several curious and sometimes funny anecdotes of such affairs at museums and picture exhibitions, where the damage had been so great as to induce the authorities to call him in to discover the offender. The work was not always easy, chiefly from the mere absence of intelligible motive; nor, indeed, always successful. One of the anecdotes related to a case of malicious damage to a picture—the outcome of blind artistic jealousy—a case which had been hushed up by a large expenditure in compensation. It would considerably startle most people, could it be printed here, with the actual names of the parties concerned.

Ivy Cottage, Finchley, was a compact little house, standing in a compact little square of garden, little more than a third of an acre, or perhaps no more at all. The front door was but a dozen yards or so back from the road, but the intervening space was well treed and shrubbed. Mr. Douglas Kingscote had not yet returned from town, but the housekeeper, an intelligent, matronly woman, who knew of his intention to call in Martin Hewitt, was ready to show us the house.

"First," Hewitt said, when we stood in the smoking-room, "I observe that somebody has shut the drawers and the bureau. That is unfortunate. Also, the floor has been washed and the carpet taken up, which is much worse. That, I suppose, was because the police had finished their examination, but it doesn't help me to make one at all. Has anything—anything at all—been left as it was on Tuesday morning?"

"Well, sir, you see everything was in such a muddle," the housekeeper began, "and when the police had done——"

"Just so. I know. You 'set it to rights,' eh? Oh, that setting to rights! It has lost me a fortune at one time and another. As to the other rooms, now, have they been set to rights?"

"Such as was disturbed have been put right, sir, of course."

"Which were disturbed? Let me see them. But wait a moment."
